For completeness: ATM all code that was byte compiled gets native
compiled automatically.  For this reason it *has* an effect since Emacs
starts.

It is true that from a user perspective everything is going on
transparently but the side effect of the native compilation is the exact
reason why people are using it (read depending on the workload it can be
noticeably faster).

If it's more or less important than say using Cairo that's very much a
POV I think, as I believe is classifying it as "minor feature" (reason
why I'd avoid).
